Click library

  • Author : MikroE Team
  • Date : Jun 2020.
  • Type : GPIO type

Software Support

We provide a library for the Scanner Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for Scanner Click driver.

Standard key functions :

  • Config Object Initialization function.

    void scanner_cfg_setup ( scanner_cfg_t *cfg );

  • Initialization function.

    SCANNER_RETVAL scanner_init ( scanner_t ctx, scanner_cfg_t cfg );

Example key functions :

  • Pulse function.

    void scanner_clock ( scanner_t *ctx );

  • Write function.

    void scanner_serial_write_reg ( scanner_t *ctx, uint8_t reg_adr, uint8_t write_data );

  • Read pixels.

    void scanner_read_pixel ( scanner_t ctx, uint8_t pixel_data );

Examples Description

This example reads data from Scanner clicks.

The demo application is composed of two sections :

Application Init

Initializes the driver and starts up the module.


void application_init ( void )
{
    log_cfg_t log_cfg;
    scanner_cfg_t cfg;

    /** 
     * Logger initialization.
     * Default baud rate: 115200
     * Default log level: LOG_LEVEL_DEBUG
     * @note If USB_UART_RX and USB_UART_TX 
     * are defined as HAL_PIN_NC, you will 
     * need to define them manually for log to work. 
     * See @b LOG_MAP_USB_UART macro definition for detailed explanation.
     */
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, "--->>> APP INIT <<<---\r\n" );

    //  Click initialization.

    scanner_cfg_setup( &cfg );
    SCANNER_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    scanner_init( &scanner, &cfg );

    Delay_ms ( 300 );

    scanner_startup( &scanner );
    Delay_ms ( 100 );

    scanner_serial_write_reg( &scanner, SCANNER_REG_MODE, SCANNER_DATA_NORMAL_MODE );

    for ( uint8_t data_cnt = 0; data_cnt < 3; )
    {
        scanner_serial_write_reg( &scanner, SCANNER_REG_OFFSET_LEFT + ( 2 * data_cnt ), 25 );
        data_cnt++;
        scanner_serial_write_reg( &scanner, SCANNER_REG_GAIN_LEFT + ( 2 * data_cnt ), 25 );
        data_cnt++;
    }
    log_printf( &logger, "--->>> APP TASK <<<--- \r\n" );
}

Application Task

Reads the array of 102 pixels and displays the results on the USB UART as frequently as possible.


void application_task ( void )
{
    uint8_t pixels[ 102 ];
    scanner_read_pixel( &scanner, pixels );

    log_printf( &logger, "left center right\r\n" );
    for ( uint8_t cnt = 0; cnt < 34; cnt++ )
    {
        log_printf( &logger, " %u   %u   %u \r\n", ( uint16_t ) pixels[ cnt ], 
                                                   ( uint16_t ) pixels[ cnt + 34 ], 
                                                   ( uint16_t ) pixels[ cnt + 68 ] );
    }
    log_printf( &logger, "----------------\r\n" );
}

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Scanner

Additional notes and informations

Depending on the development board you are using, you may need USB UART Click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
